Communication
Cradle connector
For more information, see the
documentation provided with the
accessory. The PTC’s cradle connector allows direct connection to
an SC-1124 Desktop Cradle, a VC-1124 Vehicle
Cradle, or a CP-1124 Connector Pod. Each of these
accessories provides communication and battery pack
charging and can be connected to various external
devices.
IrDA port
The IrDA 1.0 port allows the PTC to communicate via
pulses of light to and from other IrDA-compliant
devices, such as printers and host systems.
Radio
The PTC can be equipped with one local area network
(LAN) radio or one wide area network (WAN) radio.
LAN radio options
• Direct-sequence spread spectrum radio.
• 2.4 GHz direct-sequence 802.11-compliant spread
spectrum radio.
• 2.4 GHz frequency-hopping 802.11-compliant
spread spectrum radio.
Spread spectrum radios allow the PTC to
communicate interactively in real-time with a host
computer on a radio-based local area network. They
provide secure, interference-free communication and
do not require a license for operation.
No license is required to operate a
WAN radio in the U.S. or Canada, but
you must subscribe to the
corresponding radio network (or
another DataTAC network) before
the radio can be operated.
WAN radio options
• DataTAC radio
A DataTAC radio allows the PTC to communicate
via a wide-area DataTAC communication
network.
